Kubernetes: Preserve Availability during Node Maintenance with a PodDisruptionBudget
Kubernetes PodDisruptionBudget Tutorial Kubernetes PodDisruptionBudget Tutorial: Preserve Availability During Node Maintenance This tutorial demonstrates how to use PodDisruptionBudgets (PDBs) in Kubernetes to prevent downtime during node maintenance operations. We’ll focus exclusively on the PDB mechanism and explore a series of scenarios, iteratively building a solution that handles disruptions gracefully. Understanding PodDisruptionBudgets A PodDisruptionBudget (PDB) allows…
